I fully support right-to-repair but do you need a law to repair batteries? You can buy a battery build kit for M18 tools (for example) on AliExpress that comes with everything but the cells. I'm a bit of a tool nerd and I'm not aware of any power tools that are doing DRM in their tools to prevent usage of third-party batteries but I don't mind being wrong so I know which brands to avoid.
